You can put this solution on YOUR website!
An equation must have an = sign somewhere, so this is not
an equation, and you can't solve it. You can simplify it, though.
The common denominator is 20


+%285%2A%28x%2B3%29+-+4%2A%28x-4%29%29+%2F+20+=+%28+5x+%2B+15+-+4x+%2B+16%29+%2F+20+
+%28x+%2B+31%29%2F20+ answer
My way to check the answer is: pick a value for x
I'll say +x+=+17+

+20%2F4+-+13%2F5+
+%285%2A20%29%2F20+-+%284%2A13%29%2F20+
+%28100+-+52%29%2F20+
+48%2F20+=+2.4+
and
+%28x%2B31%29%2F20+=+%2817+%2B+31%29%2F20+
+48%2F20+=+2.4+
OK
